Specification of Letters Patent.

Application filed January 19, 1920. Serial No. 852,398.

. To all whom it may concern:

Be it known that I, Pnnor FREDERICK BUTTERFEID, a subject of the King ofGrea't Britain, residing at 116 Maitland street, in the cit of Toronto, in the county of York, in the rovince of Ontario, Canada, have invented certain new and useful Improvements in Wire-Grooving Machines, of which the following is the specification.

My inventlon relates to improvements in wire grooving machines and the object of the invention is to devise a simple construction of machine which will form a plurality of grooves around a wire preparatory to such wire being formed into nails of the type] disclosed 1n my allowed application, Serial No. 275,974, allowed November 19th, 1919, and it consists essentiall of the arrangement and construction 0; parts as hereinafter more particularly explained.

Figure 1 is a plan view of my wire groovm machine.

Fig. 2 is a longitudinal section through Fig. 1.

Fig. 3 is a. cross section on line 33, Fig. 2.

Fig. 4 is a Fig. 2.

Fig. 5 is a cross section on line 5-5, Fig. 2, showing the locking plunger also in section.

Fig. 6 is an enlarged perspective detail of one of the grooving members.

Fig. 7 is a further enlarged sectional view through the grooved wire and showing the position of the rooving disks in dotted lines in relation to t e wire.

Fig. 8 is a diminutive plan view showing the feed drum and take up drum and my grooving device interposed therebetween and through which the wire passes from the feed to the take up drum.

In the drawings like characters of refer ence indicate corresponding parts in each figure.

1 indicates the base of my machine which cross section on line 44:,

and a table portion 7. The table portion 7 is provided with rectangular recesses 8 and 9 in which are located slidable blocks 10 and 11. 12 and 13 are studs carried by the blocks 10 and 11 and 14 is a stud carried by the table 7 in the stationary position.

e studs 13 and 14 are located at one side of the longitudinal center of the table and the stud 12 on the other side of the center and located intermediatel between the studs 13 and 14. 15, 16 and 17 are grooved rollers carried by the studs 12, 13 and 14. 18 is the wire which it is desired to provide with a plurality of spiral grooves extend- 111g longitudina ly thereof.

19 is a crank provided with a threaded stem 20 which. passes through a correspondingly threaded orifice in the outer wall of the recess 8. The inner end of the stem 20 bears against the block 10. 21 is a locking nut adapted to hold the stem in the adjusted position. 22 is a similarcrank provided with a threaded stem 23 which passes through the wall of the recess 9 and bears against the block 11. The stem 23is provided with a locking nut24. By means of .the crank 19 the block 10 and roller carried thereon may be adjusted cross wise of the table 7 so as to force that portion of the wire extending intermediately between the rollers 16 and 17 between such rollers so as to exert a tension on the wire.

In order to prevent the Wire being drawn out of center by the pressure of the roller 15 I have made the roller 16 adjustable and after the adjusting of the roller 15 to exert tension the roller 16 is adjusted inwardly toward the center so as to carry that portion of the Wire inwardly to maintain it in the central position.

The standards 2 and 6 are provided with hearing orifices 25 and 26. 27 is a sleeve which is turnably held in such orifices. The sleeve 27 intermediately between the standards 2 and 6 is provided with an annular flange 28 provided with radial grooves 29, 30, 31 and '32. The annular flange 28 is provided with an annular laterally extending portion 33 which is concentric with the center of the sleeve 27. Opposite each radial groove 29, 30, 31 and 32 the annular portion 33 is provided with an orifice 34 for 'aurpose whlch will hereinafter appear. is provided with bearing standards 2 and 6 he sleeve 27 is also providedwith orifices 35 which are radially opposite the orifices 34. 36 is an annular disk which fits around the annular portion 33 so as to be movable thereon, such annular disk being provided with spiral slots 37, 38, 39 and 40 the inner end of each slot being semi-circular and having its center opposite the center of the corresponding recesses 29, 30, 31 and 43 is a lug which exten s outwar from the edge ring 41 and is provided with an internally threaded orifice 44. 45 is a lug-which extends outward from the annular disk 36. 46

is an agjustable screw which is threaded into the or' ed a bearing in 52.

It will be noted that the flat face of each bar memberis set at right angles to the axis of the machine or the center of the wire 18 and that the 'j aw;members 51- are so formed as to extend at a slight incline to such axis. On each pin 52 is mounted a cutting disk 53 which is provided with ,a V-shaped cutting 54 which is adapted to engage the ex- I refer-- ably provi e four cutting disks 53 so as to tenor peri hery oft e wire 18;

formfour s iral grooves 55, 56 57 and 58 .as clearly in icated in Fig. 7 of the drawing.

The peripheryof the disk' 69; is provided opposite each orifice 70 with a notch 71. 72 is a spring [held locking plungerwhich en-- gages the notches 71 so aS to. hold the disk 69 in the exact position and the desired orifice. centered exactly opposite the central pointqbetw'e en the cuttlng'disks 53. The

' disk 69 is supported upon a standard 72. which extends upwardly from the base 1.

of my grooving device adjacent to the feed roller 73. By this means the grooving de-' vice may adjust itself so as to feed the wire on the take up roller 76 which is revolved by screw 46 is then turned so as to force the disk 36 'circumferentiall carrying the ins 59, 60, 61 and 62 inwardl toward the en of each sl0t140, 39, 38 and 3 and into the position shown in the drawing in which position the peripheral cutting edges-54 of the disks 53 are forced into the wire 18. The take up roller is then revolved drawing the wire through my device the tension device formed by the rollers 15, 16 and 17 serving to hold thewire taut as it passes between the cutting disks 53. As the wire is drawn throu h, the cutting disks, being set at a slight inc e to the longitudinal center of the wire, travel spirally around the wire the sleeve 27 carri- 'ing such cutting disk revolving within t e orifices 25 and 26 being held" in position by 0 radially outward by. means of the spiral It will thus be seen that t e pull of the,
